A three-way heat exchanger for a liquid desiccant air-conditioning system and method of manufacture. The heat exchanger includes a plurality of panel assemblies. Each panel assembly has a frame bordering a given space. The frame includes desiccant inlet and outlet ports and heat transfer fluid inlet and outlet ports. Two plates joined to the frame define a heat transfer fluid channel in the given space. The heat transfer fluid inlet and outlet ports are in fluid communication with the heat transfer fluid channel. Microporous sheets cover the outer surfaces of the plates and define a desiccant channel. The desiccant inlet and outlet ports are in fluid communication with the desiccant channel. The plurality of panel assemblies have a stacked arrangement such that a microporous sheet on one panel assembly faces a microporous sheet on an adjacent panel assembly and defines an airflow channel therebetween.

Three-way heat exchangers for liquid desiccant air-conditioning systems and methods of manufacture

A liquid desiccant air-conditioning system provides a uniform liquid desiccant flow distribution and wetting out of membranes used in the membrane-modules of the system.

Methods and apparatus for uniform distribution of liquid desiccant in membrane modules in liquid desiccant air-conditioning systems

Apparatus for forming shallow p-n junctions in silicon substrates to produce photovoltaic cells, which apparatus provides three processing chambers. An ultrasonic spray is mounted in the first processing chamber to coat a front surface of the substrate with a liquid dopant-containing material. The second processing chamber dries the coated substrates leaving a dopant-containing residue on the front surface. The third processing chamber fires the substrates in an oxygen-containing environment to diffuse the dopant into the substrate and provide a p-n junction. The apparatus conducts humidified air to each chamber to control polymerization of the dopant source and to prevent non-humidified air from entering the chambers.

Apparatus for forming diffusion junctions in solar cell substrates

Silicon solar cells are made by subjecting semiconductor substrates to a diffusion junction forming process wherein a liquid source material containing a selected dopant is sprayed onto one side of the substrates, and thereafter the substrates are fired in an oxygen-containing environment under conditions calculated to cause the dopant to diffuse into the substrates so as to form a shallow p-n junction in each substrate.
